[I2C] How to send and receive a singel comma (in char)

Projects Programming

Hi Guys.
I need your help.
I use I2c protocols to communicate two Ardus.

For example, I want to send only : “,” , a comma from master Ardu to slave Ardu.
If I write Wire.write(“,”);
I received “44” on the Slave side. If you have a look on the Ascii table, you can see that (“44”) Is the Dec spelling from a single comma.

Can you tell me please, how I can send sign that the slave Ardus interpret as a Char spelling?

Best regards

Wire.write(',');

If you get something else on the receiving end, it is the receiver code that is wrong.

the slave Ardus interpret as a Char

You program the slave to use the value of 44 as a char.

   char comma = 44;
  Serial.print(comma);
